The other day I was talking to a doctor friend of mine about the new HIV vaccine. Since he is both a doctor (8 years of college) and a conservative church-going Christian, I wanted to see which side of him would win, the doctor side or the churchy side. So I asked him if the HIV vaccine was a good idea, and after pausing a moment (I'm guessing he didn't know about the vaccine), the Christian side of him finally won out and said, "I don't think it's a good idea."
To be fair, if he didn't know about it then I didn't really give him an opportunity to ponder the situation. I know from long experience he's thinking at that point that HIV is "the gay and drug-user" disease. And so a vaccine will protect them from the consequences of their behavior. The fact that it's also spread through blood transfusions and other non-moral, non-behavioral sources apparently didn't occur to him at that time.
Is HIV a moral, and not medical, disease? I don't think so. But for some people it has become the modern form of leprosy, although with better reasons. For in past centuries leprosy was thought to be God's punishment for some unknown sins. We know from the Christian standpoint, however, that Jesus forgives all sinners. So in the modern Christian context, God does not condemn sinners to die from horrible diseases. Treating AIDS victims does not go against God's wishes. So HIV, even from that perspective, is a medical, not a moral, condition.
I may be adding a lot to "I don't think it's a good idea" that isn't really there. But the idea that HIV is the modern leprosy does exist. I remember hearing about this at one time, from preachers and the like, but not so much any more.
